The AC-4 rating of 41 A at 400 V matters if your application reverses or jogs the motor under load, which generates more arcing. Side-by-side mounting is allowed, which saves panel width when ganging multiple contactors for multi-motor groups. Dimensions are 55 mm wide, 112 mm high, 130 mm deep — a compact S2 footprint that fits standard control panel gland plates and wireways. The larger stranded capacity (25 mm²) covers the heavier feeds for the 30 kW motor circuit. Coil operates at 110 V. Pickup and dropout times are 20 to 25 ms DC. Arcing time runs 10 to 15 ms. Electrical life depends on the switching category and load current; the AC-3 maximum rate of 800 operations per hour gives a sense of the thermal duty cycle.","metaTitle":"Siemens SIRIUS 3RT1036-1BF40 Power Contactor, 30 kW at 500 V","metaDescription":"Siemens SIRIUS 3RT1036-1BF40 power contactor, Size S2, 30 kW at 500 V AC-3, 41 A at 400 V AC-4, screw terminals, DIN rail mount, IP20 front.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Contactors"],"specifications":{"Depth":"130 mm","Solid":"2x (0.5 ... 1.5 mm²), 2x (0.75 ... 2.5 mm²), max. 2x (0.75 ... 4 mm²)","Width":"55 mm","at DC":"20 ... 25 ms","Height":"112 mm","Stranded":"2x (0.75 ... 25 mm²)","Arcing Time":"10 ... 15 ms","Rated Value":"110 V","On The Front":"IP20","Initial Value":"0.8","During Storage":"-55 ... +80 °C","Of The Terminal":"IP00","at AC-1 maximum":"1 000 1/h","at AC-2 maximum":"400 1/h","at AC-3 maximum":"800 1/h","at AC-4 maximum":"300 1/h","lifecycle_stage":"current","During Operation":"-25 ... +60 °C","Fastening Method":"screw and snap-on mounting onto 35 mm standard mounting rail according to DIN EN 50022","Full-Scale Value":"1.1","Size Of Contactor":"S2","Solid Or Stranded":"2x (0.75 ... 16 mm²)","Product Brand Name":"SIRIUS","Degree Of Pollution":"3","Product Designation":"power contactor","at 24 V rated value":"10 A","at 60 V rated value":"2 A","Of Contactor Typical":"10 000 000","at 110 V rated value":"1 A","at 220 V rated value":"0.3 A","at 230 V rated value":"6 A","at 400 V rated value":"3 A","at 500 V rated value":"30 kW","at 690 V rated value":"11.4 kW","Side-By-Side Mounting":"Yes","For Main Current Circuit":"screw-type terminals","at AC-2 at 400 V rated value":"22 kW","at AC-4 at 400 V rated value":"41 A","Substance Prohibitance (Date)":"05/01/2012","at 40 °C minimum permissible":"16 mm²","at 60 °C minimum permissible":"16 mm²","Insulation Voltage Rated Value":"690 V","at 230 V at 60 °C rated value":"22 kW","at 690 V at 60 °C rated value":"66 kW","at AWG cables for main contacts":"2x (18 ... 2)","For Auxiliary And Control Circuit":"screw-type terminals","With Type Of Assignment 2 Required":"fuse gL/gG: 80 A","closing power of magnet coil at DC":"13.3 W","holding power of magnet coil at DC":"13.3 W","Surge Voltage Resistance Rated Value":"6 kV","With Type Of Coordination 1 Required":"fuse gL/gG: 160 A","at AWG cables for auxiliary contacts":"2x (20 ... 16), 2x (18 ... 14), 1x 12","operational current at AC-12 maximum":"10 A","number of NC contacts for main contacts":"0","number of NO contacts for main contacts":"3","reference code according to IEC 81346-2":"Q","Finely Stranded With Core End Processing":"2x (0.5 ... 1.5 mm²), 2x (0.75 ... 2.5 mm²)","Number Of Poles For Main Current Circuit":"3","Contact Reliability Of Auxiliary Contacts":"1 faulty switching per 100 million (17 V, 1 mA)","Thermal Short-Time Current Limited To 10 S":"400 A","Finely Stranded Without Core End Processing":"2x (0.75 ... 16 mm²)","Type Of Voltage Of The Control Supply Voltage":"DC","Required Spacing For Grounded Parts At The Side":"6 mm","contact rating of auxiliary contacts according to UL":"A600 / Q600","Installation Altitude At Height Above Sea Level Maximum":"2 000 m","Of The Contactor With Added Auxiliary Switch Block Typical":"10 000 000","For Short-Circuit Protection Of The Auxiliary Switch Required":"fuse gL/gG: 10 A","number of NC contacts for auxiliary contacts instantaneous contact":"0","number of NO contacts for auxiliary contacts instantaneous contact":"0","Of The Contactor With Added Electronically Optimized Auxiliary Switch Block Typical":"5 000 000"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=254785&mlfb=3RT1036-1BF40","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RT1036-1BF40/alternatives.json"},"ai":{"faq":[{"question":"Will the 3RT1036-1BF40 drop into a panel specified for the 3RT1036-1AB00?","answer":"Both are Size S2 contactors with the same 55 mm width and DIN rail mount, so the physical footprint is identical. The key difference is the coil voltage: the 1BF40 runs on 110 V, while the 1AB00 uses a different coil. Verify your control voltage before swapping — if the panel supplies 110 V to the coil, it's a direct mechanical fit."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RT1036-1BF40","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3RT1036-1BF40 when reusing this data.
